POLICE SIGNAL DEVICE.

Signal Devices, of which the following is a specification.

Our invention relates to transmitting si nals to a distance, and more partleulary signaling from a central police station 'or.

ofiice to a patrolman or oliicer upon a beat in order to attract his attention and cause him to communicate with the central station at times other than his regular time to report.

Our invention has for itsobject the provision of efiicient'and reliableapparatus at the patrol station, eontrolledirom the central station, to notify the patrolman to communicatewith the central station and rev ceive instructions.

The'invention 'is illustrated in the ac'conianying drawings, and will be understood v reference thereto in connection with the following description and appended claims.

'In the drawings, Figure l is a general view showing! a patrol station equipped in accordance with the invention; Fig. 2 is a front view on an enlarged scale, the pole being omitted and the fronts of the casings removed toshow the construction and arrangement of the apparatus; Fig. 3 .is a view in side elevation of the apparatus shown in Fig. 2, thewheels of the clock train being omitted to avoid complication; and Fig. 4 is a diagram of circuits.

Referring to the drawings, A is a signal arm mounted upon shaft '11- journaled in frame a, which is mounted in a suitable housing, in some conspicuous place such as near the top of a pole l. Shaft a is operatcd through bevel gears a", rod r1 and bevel gears a, by suitable driving mechanism, such as a clock train B located in a convenient place upon the pole accessible from the ground and protected by a suitable housing C. The rod of may be any desired length, according to the distance between the driving mechanism and the signal arm, andcnables us to vary this distance and the height of the pole at will.

Mounted upon the frame of the clock Specification of Letters Patent. Application filed December 13, 1907. Serial No. 406,370.

the armature (I of which is connected to a bar (1' which carries a detent (l engaging the fly (1 of the (BlOClillitll'l. The lower end of'bar J is arranged to ride upon and he supported by a cylindrical surface (i carried by wheel (1, or to drop into the notches 1i".

.Shaft a of signal arm A carries a cam I) which engages arm a of a bell-crank lever. to force the other arm 0' thereofi-nto engagement with contacts e, 6 to complete the electrical circuit ofa signal lamp e which may be located in some conspicuous place, such as the top' of the pole, 'for night indication. Lamp e'may be red and may be supplied with current from any suitable source, such as the nearest light mains 1, 2, led up through the pole'J'lVhen signal arm A is in the displayed position. cam E will close tlr. circuit-of-light e, and when in the undisplayed position. arm 0 will dro off one of the cam shoulders 3 and theliunp circuit will be opened by quick movement of arm e.

euit with push button or other switch "9 "'a Fthe cent-ral station by line conductors 3. 4. and is energized from a suitable source, such'as-battery U. telephone set 'I may be arranged at; the patrol station, in bridge or -othcr\\-'i.-'r, to the line,

train B is a controlling 'cleetro-mag'uet 1).

The telephone set may be arranged either within casing C, as shown at T, Fig. 2, or in a separatebox.

The operation of the device will be readily understood from the foregoii'ig. \Vhen the device is in its normal position ready to receive and indicate-a call. the spring of clock train B being, wound,the parts are in the position shown in Fig. 2. The operator at the central station closes switch S and there by sends current over the line toone. (or more) patrol stations. when the magnet l) is energized to attract its armature (Z. This lifts bar (1 which raises latch (l -out. of engagement with ll d, which immediately begins to revolve. Al; the same time the lower end of bar d' clears the notch d'with which it was in engagement, and the circuit of magnet D should he keptclosed long enough to allow this notch to pass beyond the bar .end, which will then rest upon and be supported by the surface cl o'n wheel (P. The motion of the clock train, thus released, rotates the signal arm A and cam disk E through gears a a and rod a, until arrested by bar (l dropping into the next notch (1 thus bringing latch (i into'engagement with fly (l and sto iping the clock train. These notches are shown as four in number, so that wheel d, signal arm A, and

cam disk E are moved one-quarter of a revolution before being stopped. 'Thesignal arm A will then occupy the horizontal or displayed position, and contacts a will be bridged by arm e, to lightlamp 0". The patrolman may now talk to central and receive his orders; and the apparatus restored to normal by another nn pulse through mag nebD.
